A New Mouse Model of Psoriatic Arthritis
Bibliographic record
Abstract
locus encoding the A20 protein are strongly associated with psoriatic skin and joint disease. Reduced A20 expression, driven by both genetic and epigenetic factors, underscores its critical role as a negative regulator of psoriatic disease (PsD). Our recent study using a germline knockin mouse model harboring a mutation in A20's seventh zinc finger, which impairs A20 binding to linear (M1) ubiquitin, revealed a spontaneous phenotype resembling psoriatic arthritis. These mice demonstrated sustained nuclear factor-κB signaling in response to transient tumor necrosis factor stimulation, leading to inappropriate transcription of mid- and late-response inflammatory genes. These findings highlight the role of dysregulated innate immune-signaling kinetics as a potential driver of PsD pathogenesis. These findings, together with distinct inflammatory mouse models resulting from temporally extended inflammatory gene activation, highlight the role of dysregulated innate immune-signaling kinetics as a potential driver of tissue inflammation with relevance to psoriatic skin and joint disease. This newly developed mouse model of PsD was presented at the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2024 annual meeting.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
